52 NORTH AMERICAN BLATTIDAE 



Species, as well as from lutea minima, the present race may be 

 distinguished, in the male, by having the distal margin of the sub- 

 genital plate between the specialized styles broadly and rather 

 weakly produced, the produced portion forming a strongly trans- 

 verse rectangle. Females of lutea lutea can be separated from 

 those of lutea minima only by their average larger size and less 

 abbreviate tegmina. These features readily distinguish lutea lutea 

 from any other form found over the regions here under consider- 

 ation; a full description with extensive comparisons has recently 

 been published."

The extremes given appear to be due almost wholly to indi- 

 vidual variation. 



The young of this species have the markings of the head and 

 pronotum averaging more intensive than in the adults, with dorsal 

 surface of abdomen dark, maculate with ochraceous-buffy mesad 

 and laterad.*'^ 



The species is in large part terrestrial, being usually found 

 among dead leaves and litter on the ground. Occasional speci- 

 mens are, however, sometimes beaten from bushes. Individuals 

 are decidedly active and are usually found in the greatest numbers 

 in sandy situations.

^^ In the generic study by the author, two very small immature examples of Farcoblatta 

 sp. indet. from Southern Pines, North Carolina and Atlantic Beach, Florida, and one 

 immature individual of Chorisoneura texensis Saussure and Zehntner from Natchez, 

 Mississippi, were unfortunately recorded as this insect. These incorrect determina- 

 tions do not affect the known distribution of the race, which distribution is defined by 

 the records given below and the Louisianan and Cuban examples mentioned above. 

 The coloration of the young of lutea is distinctive.
